You need an OpenGL port with support of ZDoom extended nodes, hi-res textures and tall patches.

GLBoom-Plus with gamma 1 is recommended.

Command line: glboom-plus FrozenT.wad -complevel 9

WARNING! You need a powerful computer to play this wad. Currently it's playable only with the GLBoom-Plus and more or less acceptable with the GZDoom. Even do not try to run it in software mode. Sorry for that.
